Abstract :
An active transition from rectangular waveguide to microstrip line, operating in X-band with a GaAs MESFET as integral part of the transition is presented. The design allows for low noise amplification of the signal with improved bandwidth compared to the corresponding passive transition. Measured results of noise figure and power gain are given.<>
